This is definitely one of those "oldie but goody" recipes. Watergate Salad was all the rage back in the late 1970's and on into the eighties. It seemed any church potluck, family reunion, or after funeral spread would always have a Watergate Salad. I have researched and looked all over to find out where this salad got it's name. One can surmise it had something to do with the political scandal, but there is actually no proof that it does. From all accounts I have read, no one really knows…
